Hi guys, I'm begining to contemplate my 2nd Mac purcahse. My 12" PB has served me well but I think it will be due an upgrade soon. Since my employers are kind enough to give me a quite reasonable Toshiba laptop I'm thinking I would get more productivity out of an iMac. I've recently seen as much as 35% off the retail price for the 20" Core Duo on Apple's refurb site. Do you I should snap a deal like this up or save for a few months more and get the Core 2 Duo? Will be used for light creativity and general iLife apps.
